Here is the article with your exchange Huynh Thanh Hong in Village Lo Co B, An Truong A, Kowloon district (Tra Vinh), which represents hundreds of farmers asked: "Fertilizer and various nutrients not ? How to identify surplus or deficit of nutrients? ". Prof. Mai Van Quyen, former Deputy Director of the Institute Southern Agricultural Scientific Answer: Rice and other crops are many different qualities needed to sprouting, rooting and development branches, leaves, flourish, fruit ... Scientifically proven, plants need 16 essential minimum include C, H, O ... Other substances plant from the soil, rainfall, irrigation water and a sizable portion provided by humans. These substances include nitrogen (N), phosphorus (P), potassium (K) by the number of trees needed more so-called multi-volume substances. The use of fewer trees like Ca, Mg, S or Si is secondary matter. Besides having many qualities but the plant needs very little amount, but also extremely important as Fe, Cu, Mn, Mo, Zn, B, Cl called micronutrients. Scientists also coupling agents Ca, Mg, S and Si in nature macro group, because these substances have to be provided tens or hundreds of new sign or older, meet for plant use. And scientists have classified all of the above is the essential nutrient, not only the new N-called nutrients like you asked. These substances are known as nutrients, but each one has a very different function, so when the excess or deficiency are also manifest in different forms. Examples of nutrient N is not just for plants that need both to humans, cattle, small creatures ... In the tree, N participated in many sectors, but especially the composition of chlorophyll continent, is very important for the process of photosynthesis. Lacking chlorophyll, the photosynthetic plant photosynthesis is poor or not, the lack of trees to live, to grow slowly. N are also part of nature protit. Protit which is a manifestation of life, where there is substance in that protit life. When the trees are green, the N uptake, foliage grows rapidly developing, expressed strong vitality. In contrast, the tree when the tree lacks N yellow, slow-growing foliage and weak. So you can clearly distinguish the excess or shortage tree N easy. Due to the N application makes easy green tree, so farmers thought that any more green as well, so much abuse fertilizer N. As much N fertilizer plants, the more green leaves, the more water attraction, cell strong division and very soft. Without K, Ca and Si, the weaker trees very easily be influenced by many factors that harm the trees, especially trees very susceptible to lodging. P is also essential nutrient, but when excess or lack of the other manifestations of N. When the excess fertilizer P, you also difficult to distinguish, only healthy plant roots, lush foliage. But the lack of P is less grown, the trees heavy lack of growth also slowed, leaf edges were hard, poorly developed root system, especially the leaf tip and edges of purple blood instance expression is clear, especially in maize. K is a nutrient involved in the transportation process carbohydrates from stems, leaves to flowers, roots and fruits. K makes rigid plant cells. Excess K fertilizers are difficult to distinguish, only hardy tree, healthy. But the lack of old K burnt leaf edges, plant growth is weak, switch to dry and die. The other nutrients in the absence of manifest also are very specific symptoms and the ultimate outcome is less grown susceptible to disease, low yield. So working in the fields, planting, remember to complete and balanced fertilizer substances are high yield, stability, high economic efficiency and environmental new clean also. Buffalo Head fertilizer types are achieved when using such standards
